These are Triassic mudstones exposed in a road cut north of the Grand Canyon, on the Kaibab Plateau. Features you should note and trace are: 1) some distinctive bedding horizons, 2) the larger and smaller fault sets, 3) joints (fractures without offset), and 4) bending of strata near the fault.

Questions that may be raised are as follows. How many fault sets are there and do they relate to each other? What is the relationship between the faults and the joints?
